Not only have I done what you've just said, but at Koopa Cape, going down the waterfall I mistimed dropping my fake item box and ended up dropping it while I was falling down, which meant it landed on my head.

I was at the end, 3rd lap, I throws 7 blue shells at the person in 1st place,And then right at the end i got baaad lag and i kept pressing the up button on teh D-Pad and when it unfroze the blue shells kept hitting me over and over until i was last, My bad..

On Koopa Cape (which I hate) *leers at Cam angrily* I went up the quarter-pipe boost ramp at the start of the race and ended off shooting down the ramp and then down a cliff. I could've steered to the left out of the way but I couldn't care less.

That story is so not true. Asides from the fact that it makes absolutely no sense, if you actually knew how to hack, you'd know that you can only have 3 blue shells in the air at a time, otherwise they will start disappearing. And why did the blue shells start hitting you? The lag made you get into first place randomly? That makes zero sense.
